You're welcome. I pushed my patch adding PYTHONMALLOC environment variable:
https://docs.python.org/dev/whatsnew/3.6.html#pythonmalloc-environment-variable

Please test PYTHONMALLOC=debug and PYTHONMALLOC=malloc with your
favorite application.

I also adjusted code (like code handling PYTHONMALLOCSTATS env var) to
be able to use debug checks in all cases. For example, debug hooks are
now also installed by default when Python is configured in debug mode
without pymalloc support.
